CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation-in-part application which claimspriority to U.S. Utility patent application Ser. No. 15/436,482, filedFeb. 17, 2017, which claims priority to U.S. Provisional PatentApplication No. 62/296,659, filed Feb. 18, 2016, the contents of both ofwhich are hereby incorporated by reference in their entirety.

TECHNICAL FIELD AND BACKGROUND OF THE INVENTION

The present invention relates generally to aircraft seating suites andmore particularly to passenger suite arrangements that provide unimpededaisle access for each passenger. The suite arrangements are particularlyintended for narrow body, single aisle passenger aircraft, such as, forexample, Boeing 737 and 757 aircraft and Airbus A319 and 320 aircraft.This general class of seating is referred to as “compressed businessclass.” Embodiments of the invention permit enhanced business classseating in these and other narrow body aircraft, increasing passengercomfort while affording the aircraft operator the ability to charge ahigher fare for a seat with greater comfort and additional amenitiessuch as a privacy wall, lie-flat capable seat, ottoman, audio/videoequipment, table, closet and charging station for portable electronicdevices, among other amenities. Suites are most often found on wide-bodyaircraft where more space is available for accommodating the travelpreferences of premium class passengers who can afford to pay higherfares for more space, privacy and conveniences. While the invention isdescribed in relation to a 5-abreast passenger suite arrangement for asingle aisle aircraft, similar suite arrangements can be used forwide-body aircraft having two aisles and therefore capable ofaccommodating a larger number of abreast seats, as described below.

In all seating classes, there is a need to arrange the seats to maximizedensity without compromising space and privacy. On current wide-bodyaircraft, passenger seat ingress and egress is accomplished directlyfrom longitudinal aisles that extend through the passenger cabin. Assuch, each suite is positioned adjacent one of the aisles or in anon-aisle position requiring the seat occupant to ingress and egressthrough a laterally adjacent inboard aisle suite. This has the necessaryeffect of interrupting the privacy of the passenger seated in theinboard aisle suite as the outboard passenger passes through the seatingarea of the inboard aisle suite. Such arrangements also limit the numberof suites that can be positioned abreast and may require that all of thesuites be positioned at an angle to the longitudinal axis of theaircraft or with some facing forward and some aft.

SUMMARY OF THE INVENTION

Accordingly, there is a need for an arrangement of aircraft passengersuites that allows a greater number of suites to be positioned abreastwhile at the same time allowing ingress and egress to all suites fromthe aisle without invading the privacy of other suite occupants.

There is also a need for an arrangement of aircraft passenger suitesthat allows five suites to be positioned abreast in a narrow body,single aisle passenger aircraft.

There is also a need for an arrangement of aircraft passenger suitesthat allows five suites to be positioned abreast and all facing in thesame forward or aft direction in a narrow body, single aisle passengeraircraft.

These and other advantages are achieved by providing a seatingarrangement for a cabin of a passenger aircraft that includes first,second and third suites, each including a privacy wall and a seatmovable between a seating position and a lie-flat bed position, andadapted to be laterally positioned in the aircraft cabin in respectiveadjacent outboard, middle and inboard positions. The first, second andthird suites are adapted to be positioned in a longitudinally-offsetposition in relation to each other and define respective ingress/egresspaths to a cabin aisle extending along a longitudinal axis of anaircraft. A longitudinal axis of at least the second suite defines anangular offset relative to a longitudinal axis of the cabin aisle.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT OF THE INVENTION

Referring to FIGS. 1 and 2, a series of 5-abreast seating groups 10 areshown in an orientation as installed in a cabin of a passenger aircraft,with at least one aisle 12 extending through the cabin along thelongitudinal axis of the aircraft. Each seating group 10 includes fivesuites—20, 30, 40, 50 and 60, respectively, that extend laterally fromone side of the cabin to the other. Suites 20 and 60 are denominated“outboard” or “window” suites, suites 40 and 50 are denominated“inboard” or “aisle” suites and suite 30 is denominated a “middle” suitefor purposes of this application. However, in different arrangements ofsuites there may be other groupings of the same or similar suites wherethe above nomenclature does not apply. For example, suites according tothe invention may be installed in aircraft either with no windows, or inlocations in the cabin where windows are not present.

Window suites 20 and 60 are oriented parallel to the longitudinal axisof the cabin aisle 12. According to one embodiment of the invention, theaisle suite 40 may be angularly offset relative to the aisle 12 by 3degrees, as shown in FIG. 1. Alternatively, the aisle suite 40 also maybe oriented substantially parallel to the cabin aisle 12. In each of theembodiments, each of the suites faces in the same general forwarddirection in relation to the direction of flight of the aircraft.

The middle suites 30 and aisle suites 50 each define an angular offsetrelative to the aisle 12. While the amount of angular offset may vary,the angular offset according to one preferred embodiment is 12.7degrees. In another embodiment of the invention, the aisle suites 40each define an angular offset of 3 degrees relative to the aisle 12.

Each suite 20, 30, 40, 50 and 60 includes a respective privacy wall 22,32, 42, 52 and 62, which curves around the respective suite in a mannerthat visually screens a suite occupant from an occupant of an adjacentsuite. Each suite 20, 30, 40, 50 and 60 includes a respective seat 24,34, 44, 54 and 64, each of which includes a seat back, seat bottom,armrests and deployable leg rest of known design and construction. Seats24, 34, 44, 54 and 64 are of a known type that includes occupant andflight attendant-controlled actuators that move the seats among upright,semi-reclined, reclined and lie-flat bed positions.

In one embodiment, the suites 20, 30, 40, 50 and 60 include respectivefoot wells 26, 36, 46, 56 and 66 positioned forward of the seats 24, 34,44, 54 and 64. The foot wells house respective ottomans 28, 38, 48, 58and 68 and with the seats 24, 34, 44, 54 and 64 cooperatively form thelie-flat bed when the seats 24, 34, 44, 54 and 64 are deployed into thelie-flat position.

Note that seats 24, 34, 44, 54 and 64 are very substantially laterallystaggered in relation to each other such that no seat in its uprightseating position laterally overlaps an adjacent seat in its uprightseating position. For example, seat 24 is positioned sufficientlyforward of laterally adjacent seat 34 that the front of seat 34 isrearward of the back of seat 24. This arrangement not only permits allof the seats 24, 34, 44, 54 and 64 to be forward facing in the cabin,but also provides a substantially enhanced degree of privacy to eachsuite occupant in both the upright seating and lie-flat sleepingpositions.

By continued reference to FIGS. 1 and 2, the arrangement described abovepermits each of the five suite occupants in each seating group 10 tomove to and from aisle 12 without passing through the space of any othersuite. Passengers assigned to window suites 20 can ingress and egressalong a path behind the privacy walls 32 and 42 of suites 30 and 40.Passengers assigned to the middle suites 30 can ingress and egress alonga path behind the privacy wall 42 of suite 40 and, of course, theoccupants of aisle suites 40 can ingress and egress directly into aisle12, as can the passengers assigned to aisle suites 50. Passengersassigned to window suites 60 can ingress and egress along a path behindthe privacy wall 52 of suites 50. Arrows in FIG. 1 show the pathdirection for each of the above examples.

The pitch of the seats is variable but preferably fall within the rangeof 32″-38″ (82 cm-97 cm) with 33″ (84 cm) being one such pitch value.Additionally, it is not required that the pitch of each seat 24, 34, 44,54 and 64 be the same as every other seat in the seating group 10. Pitchcan vary as required as between any two seats, generally within therange of 32″-38″ (82 cm-97 cm).

Other, enlarged views of the seating groups 10 from different aspectsare shown in FIGS. 3-5.

Referring to FIG. 6, where like reference numerals refer to likeelements, in an alternative embodiment of the invention the outboardwindow seats 24′ and 64′ are positioned at an outwardly-facing angle of3 degrees to the longitudinal axis of the aircraft cabin and the aisle12. This angle provides more comfort and increased space for the seatoccupant. In addition, this slight angle provides better alignment withthe cushion edge of the ottomans 28 and 68. In the embodiment shown inFIG. 6, the foot wells 26, 66 and ottomans 28, 68 remain in the parallelposition relative to the longitudinal axis of the aircraft cabin shownin FIGS. 1-5. As a further alternative, the foot wells 26, 66 andottomans 28, 68 can also be angled, if desired. The 3 degree angle canbe varied between 0.5 degrees and 6 degrees depending on cabindimensions and seat pitch. Note that there is sufficient space betweenthe seats 24′ and 64′ and the privacy walls 22 and 62 for the respectiveseats 24′ and 64′ to be angled as shown in FIG. 6 and within the rangeindicated.

The 5-abreast seating groups 10 can be expanded for use in wide-bodyaircraft by arranging the suites with a greater number of suitesextending laterally across the cabin. Because wide-body aircraft havetwo or more aisles, the arrangement shown in the drawings can beexpanded by installing a 3-abreast group of suites on an opposite sideof a second aisle, whereby suites 50 and 60 become a center group ofsuites and the second 3-abreast group of suites become the 6th, 7th and8th suites of an 8-abreast seating group. Other groupings are alsopossible and are within the scope of the invention, for example a2-abreast, aisle, 3-abreast, aisle, 2-abreast arrangement, and a2-abreast, aisle, 2-abreast, aisle, 2-abreast arrangement.
